Change environment variables to be case-preserving (#12701)
This PR changes `$env` to be **case-preserving** instead of
case-sensitive. That is, it preserves the case of the environment
variable when it is first assigned, but subsequent retrieval and update
ignores the case.

Notably, both `$env.PATH` and `$env.Path` can now be used to read or set
the environment variable, but child processes will always see the
correct case based on the platform.

Fixes #11268.

---

This feature was surprising simple to implement, because most of the
infrastructure to support case-insensitive cell path access already
exists. The `get` command extracts data using a cell path in a
case-insensitive way (!), but accepts a `--sensitive` flag. (I think
this should be flipped around?)
